This article supersedes TSB 6-22-7 to update the Issue Statement, vehicle model years and model line covered.

ISSUE:

Some 2005-2010 vehicles equipped with a 4R70/75E-W transmission may experience an un-commanded torque converter clutch (TCC) apply or TCC partial apply immediately after the 1-2 shift. This may result in the perception that the vehicle lacks power or that the transmission is up-shifting too early. Additional symptoms of uncommanded TCC apply when coming to a stop (before the 2-1 downshift is commanded), are engine stalling or lugging when engaging manual 2nd while at a stop and code P1742 may be present in continuous memory. However, the vehicle should operate normally in park, reverse, neutral and manual 1st gear.

ACTION:

Follow the Service Procedure for verification and repair.

SERVICE PROCEDURE

If TCC % = 0 and TC SLIP ACT = less than 20 RPM then inspect the number 7 check ball in the main control valve body for damage. Replace as required following the appropriate Workshop Manual (WSM) under Disassembly and Assembly of Subassemblies – Main Control Valve Body. (Figure 1)

If you receive any other reading, this procedure does not apply; follow normal diagnostic procedures as outlined in the appropriate WSM.

NOTE:

IT IS NORMAL FOR THE PCM TO COMMAND 4TH GEAR AT SPEEDS AS LOW AS 19 MPH ( 30 KM/H) WITH LIGHT ACCELERATION WHEN THE THROTTLE POSITION IS LESS THEN 20%.
